Top Water Heater Repairs and Installation related questions
There are several types available on the market, the most popular ones being storage tank water heaters and tankless water heaters. Heat pumps and solar-powered water heaters are used for households who are interested in more sustainable water heating systems. Meanwhile, condensing water heaters are recommended for property owners who use natural gas systems as their power source.
Not really. Taskers usually bring with them the necessary tools needed, so you don’t need to prepare anything beforehand. However, it will depend on the type of water heater you have and the actual service you need. They’ll most likely use a screwdriver, a pipe wrench, plumber’s tape, a soldering torch, and cutters. If you need them to inspect your water heater, they may also require electricity and voltage testers.
On average, water heater installations typically take a few hours to complete and longer if there are repairs needed. Some circumstances might require them to come back the next day. Take note that the installation process is also a bit longer if you are upgrading from a conventional tank water heater to a tankless model. For a more accurate time frame, feel free to ask your Tasker directly.
If you want to maximise the benefits of your water heater for as long as possible, it’s best to have it checked and drained at least once a year. We can help empty the entire tank, get rid of sediments to prevent clogging, and refill the clean water. It’s also crucial to get in touch with qualified plumbers or heating engineers immediately if you encounter any issues with your water heater system.
Definitely! You won’t have to browse online or call companies for a 24-hour water heater service. Just put up your task, and we’ll quickly connect you with the nearest plumber or technician who can come to your property and fix your water heater immediately.
Here at Airtasker, you can find plenty of specialists who can help you with a range of services. You can hire them to repaint walls, replace your bathroom flooring or tiling, or remove grouts from seams and joints. They can also help waterproof your shower enclosures to avoid accidents due to water leaks and dampness. Taskers can also help install water tanks - check out how much water tank installation costs to get an idea of pricing when booking a Tasker.

What do water heater repairs and installation services include?
Water heater services cover installation, repairs, and replacements to ensure that you're getting the most out of your equipment. Through our platform, you can find skilled and qualified technicians who can work on various water heater types and brands, and service its parts and accessories. Here's what you can expect:
Installing water heaters
A water heater is one of the most significant considerations when it comes to constructing or renovating bathrooms. Since it requires a lot of plumbing and electrical work, it's more efficient to leave the job to an expert. Water heater installers usually follow the installation process as written on the manufacturer's manual. They can help with:
- basic soldering
- connecting electrical wirings
- fastening pipe assemblies and water lines
- T&P (Temperature & Pressure) valves installation
For conventional water heaters, your installer can assist you in finding the ideal spot to place your tank. If needed, they can also inspect for leaks and set the controls of your newly installed water heater.
Repairing water heaters
At some point, your water heater will likely fade and deteriorate due to old age, overuse, or even mechanical failure. While it's inevitable, you can save more time and repair costs if you can have them checked as soon as you notice any signs of defect. Repair experts can lend a hand with minor or major hot water heater repair services so you can have your equipment running again. They can also help troubleshoot common water heater problems such as:
- noisy tanks
- leaks coming from the bottom
- water taking too long to heat
- no hot water dispensing from the faucet
- immersion heater element replacements
- Water heater replacements
Water heaters are made to last around 8 to 10 years, and longer if they're religiously maintained. But if they're no longer functioning like how they used to, then you may want to consider replacing them with newer models. Water heater specialists can take care of the entire replacement process.Â
It typically involves draining the damaged or leaking tank, removing a T&P relief valve, cutting off water supply lines, and installing a water heater. You can hire them for same-day replacement and installation service, or any day to your best convenience.
